The body 30 of the calf rest 22 may be made of at least one of a varietyof types of materials, in various embodiments. In some embodiments, thebody 30 of the calf rest 22 may be a foam body 30. In someimplementations, the foam body 30 may be expanded polypropylene foam. Insome embodiments, one or more portions of the body 30 may be comprisedof foam. For example, the first and second exterior peaks 36, 40, theinterior peak 38, and/or the first and second troughs 32, 34 may beformed of expanded polypropylene. Various types of foam arecontemplated. The calf rest 22 may include a variety of components inaddition to the body 30. For example, a trim cover 68 may generallyencapsulate the body 30, as illustrated in FIGS. 1 and 2 . As describedfurther herein, the calf rest 22 may further include the wire 60, invarious embodiments.

Referring now to FIGS. 3 and 4 , in some embodiments, the first trough32 of the body 30 may include a contoured section 42 that is disposedbetween the first exterior peak 36 and the interior peak 38 of the body30, and a sloped section 44 that is disposed between the contouredsection 42 of the first trough 32 and the interior peak 38 of the body30. The contoured section 42 of the first trough 32 may include acurved, non-planar surface 46. As illustrated in FIG. 4 , the curvedsurface 46 of the contoured section 42 of the first trough 32 extendsfrom the first exterior peak 36 of the body 30 to the sloped section 44of the first trough 32, which is adjacent to the contoured section 42.In various embodiments, the surface 46 of the contoured section 42 ofthe first trough 32 may be curved to generally contour a shape of atleast a portion of the lower leg L of an occupant of the seatingassembly 14. In some embodiments, the curved surface 46 of the contouredsection 42 may be contoured to follow the shape of the rear side of thelower leg L of a 50th percentile male mannequin. Various contours arecontemplated.

Referring still to FIGS. 3 and 4 , the sloped section 44 of the firsttrough 32 of the body 30 may have a generally planar surface 48. Asillustrated in FIG. 4 , the generally planar surface 48 of the slopedsection 44 of the first trough 32 extends from the contoured section 42of the first trough 32 to the interior peak 38 of the body 30. In theembodiment illustrated in FIG. 3 , the second trough 34 includes acontoured section 42 and a sloped section 44. The contoured section 42of the second trough 34 is disposed between the second exterior peak 40and the interior peak 38, and the sloped section 44 is disposed betweenthe contoured section 42 of the second trough 34 and the interior peak38 of the body 30. The contoured section 42 of the second trough 34includes a curved surface 46, and the sloped section 44 of the secondtrough 34 includes a generally planar surface 48. As described above inreference to the contoured section 42 of the first trough 32, thecontoured section 42 of the second trough 34 may be contoured to followthe shape of a portion of the lower leg L of an occupant seated in theseating assembly 14.

Referring still to FIGS. 3 and 4 , in various embodiments, the generallyplanar surfaces 48 of the sloped sections 44 of the first and secondtroughs 32, 34 may define planes 50 that are not parallel to each other.In various implementations, the plane 50 of the surface 48 of the slopedsection 44 of the first trough 32 and the plane 50 of the surface 48 ofthe sloped section 44 of the second trough 34 may intersect to form anangle θ. In some embodiments, the angle θ formed may be between about30° and about 90°. In some embodiments, the angle θ formed may bebetween about 45° and about 75°. In some embodiments, the angle θ formedmay be about 60°, as illustrated in FIG. 4 . In the embodimentillustrated in FIGS. 3 and 4 , the sloped sections 44 of the body 30slope foam body-laterally-inboard away from the contoured sections 42toward the interior peak 38 of the body 30.

Referring now to FIGS. 1-4 , in various embodiments, a height of theinterior peak 38 of the body 30 relative to a bottom 52 of the firsttrough 32 of the body 30 may be greater than a height of the firstexterior peak 36 relative to the bottom 52 of the first trough 32.Further, the height of the interior peak 38 relative to a bottom 52 ofthe second trough 34 may be greater than the height of the secondexterior peak 40 relative to the bottom 52 of the second trough 34. Assuch, in various embodiments, the interior peak 38 may extend outwardfurther than the first and second exterior peaks 36, 40 of the body 30.In some embodiments, the bottom 52 of the first trough 32 may beshallowest proximate to the distal end 26 of the calf rest 22. Further,the bottom 52 of the second trough 34 may be shallowest relative to theinterior peak 38 of the body 30 proximate to the distal end 26 of thecalf rest 22. In some embodiments, the first and second troughs 32, 34may be deepest relative to the interior peak 38 of the body 30 proximateto the proximal end 24 of the calf rest 22. In some implementations, thevarying depth of the first and second troughs 32, 34 of the body 30between the proximal and distal ends 24, 26 may be due to the curvedsurfaces 46 of the contoured sections 42 of the first and second troughs32, 34 of the body 30 of the calf rest 22. For example, the contouredsection 42 of the first trough 32 of the body 30 may include a firstportion 56 proximate to the proximal end 24 of the calf rest 22 forreceiving the calf of a seated occupant, and a second portion 58proximate to the distal end 26 of the calf rest 22 for receiving theankle of the seated occupant. The first portion 56 may be deeperrelative to the interior peak 38 of the body 30 than the second portion58, as the calf of the seated occupant generally extends outward fromthe leg L further than the ankle.

Referring now to FIGS. 1, 2, and 5-7 , the calf rest 22 may include thewire 60. In various embodiments, the wire 60 may extend across the firsttrough 32 of the body 30 from the first exterior peak 36 to the interiorpeak 38. In some embodiments, the wire 60 may extend across the secondtrough 34 from the second exterior peak 40 to the interior peak 38. Inthe embodiments illustrated in FIGS. 5 and 6 , the wire 60 extendsacross the first trough 32 from the first exterior peak 36 to theinterior peak 38 and across the second trough 34 from the interior peak38 to the second exterior peak 40. In some embodiments, the wire 60 mayextend from the interior peak 38 to the first and/or second exteriorpeaks 36, 40 across the first and/or second troughs 32, 34 in a calfrest-lateral direction. The calf rest-lateral direction may be generallyperpendicular to the direction that the calf rest 22 extends from theproximal end 24 to the distal end 26. As illustrated in FIGS. 1 and 2 ,in some embodiments, the calf rest 22 may include a plurality of wires60 that extend across the first and/or second troughs 32, 34.

The wire 60 illustrated in FIG. 5 is shown in the at rest condition, butthe wire 60 may be configured to be operable between the at restcondition and a contracted condition. This is due to the wire 60 being ashape memory alloy wire that thermally actuates when exposed to anelectric current. Shape memory alloy wires contract to the contractedcondition when exposed to a current, and return to their originallengths in the at rest condition when the current is removed. Theoperability of the wire 60 of the calf rest 22 to contract may provide amassage feature for the calf rest 22, as described further herein.

Various types of wires 60 operable between at rest and contractedconditions are contemplated (e.g., nickel titanium alloy, shape memorypolymer wires, etc.). The wire 60 of the calf rest 22 may be coupled toan electric current source 62, such as a battery, and a controller 64that is configured to control the application of the current to the wire60. It is contemplated that the controller 64 may prompt current to beprovided to the wire 60 in response to one or more of a variety ofinputs. For example, the controller 64 may receive an input signal froman input feature 66 (e.g., switch) of the seating assembly 14 thatindicates the occupant’s desire for actuation of the massage system ofthe calf rest 22. In response to receiving the input signal, thecontroller 64 may prompt current to be intermittently applied to thewire 60 to move the wire 60 between the at rest and contractedconditions repeatedly.

Referring now to FIGS. 5 and 6 , the wire 60 may contract due to theapplication of current, such that the wire 60 is shorter from end to endin the contracted condition relative to the at rest condition. In someembodiments, wherein the wire 60 extends across the first trough 32 ofthe body 30 from the first exterior peak 36 to the interior peak 38, thewire 60 may extend along the contour of the first trough 32 between thefirst exterior peak 36 and the interior peak 38 while in the at restcondition. In such embodiments, the wire 60 may be suspended from thefirst exterior peak 36 and the interior peak 38 over the first trough 32of the body 30 in the contracted condition. In the embodimentillustrated in FIGS. 5 and 6 , wherein the wire 60 extends across thefirst trough 32 of the body 30 from the first exterior peak 36 to theinterior peak 38 and across the second trough 34 of the body 30 from theinterior peak 38 to the second exterior peak 40, the wire 60 may extendalong a contour of the first trough 32 between the first exterior peak36 and the interior peak 38 and along the contour of the second trough34 from the interior peak 38 to the second exterior peak 40 while in theat rest condition. Further, in the contracted condition, the wire 60 maybe suspended from the first exterior peak 36 and the interior peak 38over the first trough 32 and may be suspended from the interior peak 38and the second exterior peak 40 over the second trough 34 of the body30. As illustrated in FIGS. 5 and 6 , the shortening of the wire 60 thatresults from the wire 60 entering the contracted condition causes theportions of the wire 60 that extend across the first and second troughs32, 34 to extend upward away from the first and second troughs 32, 34 ofthe body 30. As described further herein, this upward movement of theportions of the wire 60 extending across the first and second troughs32, 34 may apply pressure to the lower legs L of the seated occupant.

In operation of an exemplary embodiment of the seating assembly 14, thecalf rest 22 of the seating assembly 14 may initially be in theretracted position and a plurality of wires 60 extending laterallyacross the body 30 of the calf rest 22 may initially be in at restconditions. The occupant of the seating assembly 14 may then move thecalf rest 22 to the deployed position and actuate a calf rest massagesystem input feature 66 of the seating assembly 14. In response toactuation of the input feature 66, the controller 64 may prompt currentto be selectively provided to each of the plurality of wires 60 of thecalf rest 22. Each of the wires 60 is positioned between the expandedpolypropylene foam body 30 of the calf rest 22 and the trim cover 68 ofthe calf rest 22 that generally encapsulates the body 30. Each of thewires 60 extends laterally across the first trough 32 of the body 30from the first exterior peak 36 to the interior peak 38 and across thesecond trough 34 of the body 30 from the interior peak 38 to the secondexterior peak 40. In the at rest conditions, the wires 60 extend alongthe contours of the first and second troughs 32, 34 between the interiorpeak 38 and the first and second exterior peaks 36, 40. When current isapplied to the wires 60, the wires 60 shift to the contracted conditionand shorten, which causes portions of the wires 60 that extend acrossthe first and second troughs 32, 34 to be suspended between the interiorpeak 38 and the first and second exterior peaks 36, 40 of the body 30.As the wires 60 repeatedly move between the rest and contractedconditions, they intermittently press against the rear sides of theseated occupant’s legs L to create a massaging effect.

The present disclosure may provide a variety of advantages. First, thebody 30 being formed of foam with a relatively high indentation loaddeflection value, such as expanded polypropylene, may allow the interiorpeak 38 and first and second exterior peaks 36, 40 to better withstandthe forces applied by the wire 60 as the wire 60 enters the contractedcondition compared to low indentation load deflection value foams thatare typically associated with seating assembly cushions. Second, thesloped sections 44 of the first and second troughs 32, 34 of the body 30being generally planar and extending at laterally-inboard angles fromthe contoured sections 42 to the interior peak 38 may (1) enable thefirst and second troughs 32, 34 to comfortably accommodate legs L ofvarious girths, and (2) cause the wire 60 to press against the rearsides of a seated passenger’s legs L rather than pinching against theleft and right sides of the seated occupant’s legs L when moving fromthe at rest condition to the contracted condition.
